i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell.

ii)leakage flux is the loss at flux but linkage flu is warning flux.

iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.

when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.

In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads. So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux. Now, flux is directly proportional to Voltage and Current. When Current increases due to increased load (and voltage remains same): Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant. When Primary Voltage is increased: Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not. That's how In transformer core flux depends on voltage whereas leakage flux depends on current.

Any magnetic flux generated by the primary winding that doesn't link with the secondary winding is called 'leakage' flux.

leakage reactance in induction motor depends on the reluctance of the path in which the leakage flux is establishing. with the increase in stator current the leakage flux also increases but it cannot maintain linear relationship because of saturation of the leakage flux path, even though current is increasing the flux will not increase and it'll be constant after saturation. this leakage flux links with the stator winding and induces emf which will be opposite to the supply voltage causes drop in applied voltage , the drop in the applied voltage is represented with the leakage reactance. as flux is responsible for the induction of emf , the increase in current does not increase flux after saturation and therefore emf also doesnot increase so the leakage reactance is not constant throughout the machine operation...

The leakage flux is the magnetic flux that escapes the armature of the transformer and thus does not provide coupling from the primary windings to the secondary windings. If not minimized it can be a significant cause of energy loss and inefficiency in transformers.

An ideal transformer is the one whose windings do not have any ohmic resistance and whose core does not have any leakage flux and eddy current losses.A practical transformer is the one whose windings do have some amount of ohmic resistance and the core also have some leakage flux and eddy current losses.

Then the leakage flux will be reduced as leakage flux is iversely propertional to window factor i,e height to width ratio of the window. As height is more & width is less then the leakage flux ll travel through low reluctance path i,e core itself and it adds with the main flux or working flux.

To maximise the magnetic linkage and flux density between the primary and secondary windings.

For better flux linkage and for least losses

As happens with voltage and current, flux is steady for dc but keeps altering for ac. A transformer works through the ac flux in the magnetic core.

The phase shift is caused by inductance in the transformer. Any inductance from magnetic flux that fails to link both windings is called leakage flux, and the resulting inductance is called leakage inductance.

Flux helps promote soldering. Soldering paste might contain flux and other items to help promote soldering. The paste helps hold the flux in place while beginning to solder.

Flux linkage is determined by magnets. The constant flux (Wb) per pole pairs induced in the stator windings of the magnets. Flux established by the permanent magnets produce three trapezoidal back EMP waveforms.

It's usually 68 degrees. Plus or minus 1.AnswerIf you are referring to the difference between an 'ideal' transformer's primary voltage and the resulting flux in the core of that transformer, then the voltage leads the flux by 90 degrees.

In Power Transformer in higher rating to minimise the Stray losses (losses caused by leakage flux linking with structural part- tank - yoke plates) Tank shunts shunt the leakage flux and contains it within. shunts are made of CRNGO.

in case of cumulative generator series field flux and main field flux are of same direction and in case of a differential compound generator series field flux and main field flux opposes each other.

The leakage reactance is one of the components of the reactance in the input impedance that is there when the load impedance is purely resistive. The leakage reactance is due to flux that fails to link both the primary and the secondary windings.

damper winding help to maintain the magnitude phase shift (on load chages) between rotor an stator flux and kill some parasite currents produced by the leakage flux moving out the rotor winding to the rotor core.
